First project: ī99 Saab 9-3 Viggen Convertible

This is the first Viggen I worked on. Itīs a MY 99 Saab 9-3 Viggen Convertible in black with flame ochre interior.

Being a Saab show car, it has not been registered for road use before 17th april 2000. First registered owner was Saab of Germany.
I bought the car in december 2002. It had covered 52.000 km at that time.

Those are the only purely esthetic modifications to the car. All other modifications serve the purpose of improving the carīs street and track performance.

Wheels, suspension and brakes

Stock springs have been replaced with H&R springs to lower the car. This really transformed the chassis, which is quite capable now even with the stock Sachs dampers (which are exclusive to the Viggen).

In november 2003, the original 308mm front brake has been upgraded using Ferrodo DS2500 performance brake pads

In may 2005, the original front brakes have been upgraded using 332x28mm Hirsch Performance brake discs, Porsche 996 GT3 4-piston aluminium-monobloc calipers made by Brembo and custom made steel caliper carriers made by Frank Grauer.

After major problems with brake squeal and poor track performance, the Hirsch Performance brake discs have been replaced with 323x32mm Porsche 993 biturbo brake discs with custom made bells made by BSP and the calipers have been modified by BSP in july 2005.

In september 2006, an all-new brake kit by BSP has been installed (323x32mm Porsche 993 biturbo brake discs with custom made bells, modified Porsche 996 GT3 4-piston aluminium-monobloc calipers made by Brembo and custom made aluminium caliper carriers) and
the original 286x10mm rear brakes have been upgraded using 300x20 Saab 9-5 Aero MY2002-now brake discs, cross drilled Porsche-style by BSP, Saab 9-5 Aero rear calipers and custom made brake lines by Taliaferro.

In october 2005 (110.000 km), the gearbox has been rebuild by Heuschmid, using original Viggen parts and a special upgrade kit designed for the Hirsch 9-5 Troll R gearbox to make it stronger, modified to fit the Viggen gearbox (which is different in many parts from both the 9-3 and the 9-5 gearbox).
